Making faces on Fourty-Four Fifty

Description 

Clamshell Cave hosts a variety of moderate climbs, including some enjoyable moderate cracks. Most of the lines are either trad lines or require trad gear. It is easily possible to toprope most of the lines by scrambling around the right side of the crag. Most routes end at bolted anchors. The hangers on the anchors seem to come and go, a definite nuisance since options for gear at the top of the crag aren't great. Be prepared to use the anchor on a neighboring route.


Getting There 

Park 5.4 miles up Icicle creek canyon and look for a trail on the north side of the road. A well travelled and sometimes braided trail reaches the base of the crag in 10-15 minutes.

The anchors on this crag have hangers, but (strangely) no quicklinks for lowering. I have seen ropes get stuck when people attempt to pull them after rappelling, necessitating a hike around to the top of the crag. If anyone is so inclined, adding quicklinks to the anchors would be a nice improvement to the area.
